Some are calling it the deadliest outbreak in history. And as the Ebola virus continues to spread in West Africa, the question is if and when it will be contained.

"The virus is now linked to 121 deaths ... There is no vaccine and no cure for Ebola. Health leaders say the current outbreak could last several months." (Via KWCH)
In the past, Ebola outbreaks have plagued parts of Uganda. The World Health Organization says the worst was in 2000 when 425 people became infected from the virus and more than half died. (Via World Health Organization)
But the organization says the situation in Guinea is one of the most challenging Ebola outbreaks it's ever faced.
That's because it has spread so quickly — first starting just weeks ago in a remote village of Guinea, then escalating to the capitol of Conakry and crossing into Liberia and Sierra Leone. (Via CIA)
Conakry alone has a population of about 2 million. The fear is the virus will keep spreading.

Ebola is transmitted from direct contact. Symptoms of the virus include diarrhea, vomiting, and fever. But it's the internal bleeding that can often cause death. On average, 70 percent of people infected die fron the virus.
Right now, there is not a cure. Promising vaccines and medications are in the works, but are still years away from availability. (Via CBS)
Progress has been made. Now doctors can test for the virus when outbreaks occur, something they couldn't do three years ago. (Via BBC)
Though, the World Health Organization reports this outbreak is far from contained. CNN's chief medical correspondent Sanjay Gupta says 42 days must passe without a new Ebola case for the outbreak to end.
